Vitis Vinifera (Grape) Juice
Grape juice
No meaningful concern for most people; irritation is possible but rare.
Also written as: Grape Juice · Vitis Vinifera Fruit Juice
What it is
This is juice pressed from grapes, containing water, natural sugars such as glucose and fructose, and organic acids including tartaric and malic acid. The sugars behave as mild humectants and the acids can lower a formula's pH slightly, so juice is not quite interchangeable with grape water. As with grape water, the concentrated polyphenols associated with grapes sit mainly in the seeds and skins, not the juice.
What it does well
Adds natural sugars that hold a little water in the skin
Grape sugars act as weak humectants. The effect is modest compared with a dedicated humectant like glycerin, which is usually also present.
Limited evidence
Worth knowing
Fruit acids can make a formula slightly acidic
Tartaric and malic acid from grape juice can nudge a product's pH down. In a well-made mask this is buffered, but very acidic fruit-based formulas can sting sensitised skin.
Matters most toPeople with reactive skin who already find acid toners uncomfortable.
